1 Celecoxib activates PI-3K/Akt and mitochondrial redox signaling to enhance heme oxygenase-1-mediated anti-inflammatory activity in vascular endothelium. Celecoxib heme oxygenase 1 Homo sapiens
2 This led us to the hypothesis that celecoxib induces the vasculoprotective enzyme heme oxygenase-1 (HO-1). Celecoxib heme oxygenase 1 Homo sapiens
3 This led us to the hypothesis that celecoxib induces the vasculoprotective enzyme heme oxygenase-1 (HO-1). Celecoxib heme oxygenase 1 Homo sapiens
4 In human umbilical vein and aortic endothelial cells, 24-48 h treatment with celecoxib induced HO-1 mRNA and protein expression and increased HO-1 enzyme activity. Celecoxib heme oxygenase 1 Homo sapiens
5 In human umbilical vein and aortic endothelial cells, 24-48 h treatment with celecoxib induced HO-1 mRNA and protein expression and increased HO-1 enzyme activity. Celecoxib heme oxygenase 1 Homo sapiens
6 Furthermore, celecoxib-induced HO-1 was inhibited by dominant-negative Nrf2. Celecoxib heme oxygenase 1 Homo sapiens
7 The functional significance of HO-1 induction was revealed by celecoxib-mediated inhibition of VCAM-1 expression, a response reversed by the HO-1 antagonist zinc protoporphyrin. Celecoxib heme oxygenase 1 Homo sapiens
8 The functional significance of HO-1 induction was revealed by celecoxib-mediated inhibition of VCAM-1 expression, a response reversed by the HO-1 antagonist zinc protoporphyrin. Celecoxib heme oxygenase 1 Homo sapiens
9 HO-1 induction provides a molecular mechanism for clinical observations indicating relative freedom from atherothrombotic complications in patients taking celecoxib compared to other NSAIDs with comparable anti-inflammatory activity. Celecoxib heme oxygenase 1 Homo sapiens
